The invention relates to switching equipment (1, 1a, 1b, 1c, 1d) comprising a housing (2, 2a, 2b, 2c, 2d), at least one contact point (4, 4a, 4b, 4c, 4d) that has a fixed and mobile contact part (8, 8a, 8b, 8c, 8d; 6, 6a, 6b, 6c, 6d) and an electromagnetic trip device (20, 20a, 20b, 20c, 20d) comprising a trip coil (22, 22a, 22b, 22c, 22d) and a trip armature (24, 24a, 24b, 24c, 24d). Said equipment is characterised in that the trip armature (24, 24a, 24b, 24c, 24d) is configured from a material with magnetic shape memory properties. According to the invention, when a short-circuit occurs, the trip armature (24, 24a, 24b, 24c, 24d) is deformed by the influence of the magnetic field of the trip coil (22, 22a, 22b, 22c, 22d), thus causing the contact point (4, 4a, 4b, 4c, 4d) to open.

The invention relates to switching equipment (1) comprising a housing (2), at least one contact point (4) that has at least one fixed and one mobile contact part (8, 6) and an electromagnetic trip device (20, 20a, 20b), comprising a trip coil (22, 22a, 22b) and a hammer armature (26, 26a, 26b). Said equipment is characterised in that the electromagnetic trip device (20, 20a, 20b) comprises a snap body (24, 24a, 24b) consisting of a material with magnetic shape memory properties, which interacts with the hammer armature (26, 26a, 26b). According to the invention, when a short-circuit occurs, the snap body (24, 24a, 24b) is switched between two bi-stable positions by the influence of the magnetic field of the trip coil (22, 22a, 22b).

Die Erfindung betrifft ein elektrisches Schaltgerät, insbesondere Leitungs-, Motor- oder Fehlerstromschutzschalter, mit einem thermischen Auslöser, mit einem elektromagnetischen Auslöser, mit einem Schaltwerk mit einer Verklinkungsstelle und wenigstens einer Kontaktstelle, die mittels des Schaltwerkes bleibend geöffnet oder geschlossen wird, mit einem Schaltgriff, der mittels eines Kupplungselementes mit einem Ende einer Lasche verbunden ist, deren anderes Ende mit einem das bewegliche Kontaktstück tragenden Kontaktträger gekoppelt ist, und mit einem Klinkenhebel, der mit einem Auslösehebel die Verklinkungsstelle bildet. Der Kontaktträger für das bewegliche Kontaktstück befindet sich zwischen dem thermischen und dem elektromagnetischen Auslöser. Der Klinkenhebel bildet mit einem drehbar gelagerten, mit dem elektromagnetischen Auslöser und dem thermischen Auslöser zusammenwirkenden Auslösehebel die Verklinkungsstelle. Der thermische Auslöser ist mittels einer den Kontaktträger übergreifenden Verbindungsstange mit dem Auslösehebel gekuppelt, so dass sowohl der thermische als auch der elektromagnetische Auslöser bei einem Über- und/oder Kurzschlussstrom die Verklinkungsstelle öffnen.

47 ELECTRICALLY-CONTROLLED ACTUATOR DEVICE, AND WASHING AGENTS DISPENSING DEVICE COMPRISING SUCH AN ACTUATOR DEVICE PCT/EP2012076303 2012-12-20 WO2013092813A3 2013-09-12 MARONE GIUSEPPE; DAMILANO SERGIO
The actuator device (1) comprises: - a stationary support structure (2, 3), - a movable member (5) displaceable relative to said structure (2, 3), and - a wire (SMW) of a shape-memory material, which extends in the structure (2, 3) between two anchoring elements (15, 16) and the movable member (5, 6) such that the wire (SMW) shortens when an electric current flows therethrough, causing a displacement of the movable member (5, 6) against the action of a contrast member (8). In the structure (2, 3) there are provided two deflection members (21, 22; 23, 24) disposed along the path of the shape-memory wire (SMW), each one between the movable member (5, 6) and the corresponding anchoring element (15, 16) of the wire (SMW), such as to cause a deflection of the wire (SMW) between each anchoring element (15, 16) and the movable member (5, 6).

The present invention relates to actuators, linear motors and rotational motors based on magnetic-field-induced strains taking place in the actuator material. These strains are caused by the reorientation of the twin structure of the actuator materials by the applied magnetic field.
